Great value for money. I wanted to purchase a memory foam mattress to put in our attic bedroom, as the tight staircase made it difficult to get a normal mattress in. I was sceptical of this mattress at first due to the low cost and it was very thin when it arrived. However, 2 weeks later and I don't think I've ever owned a more comfortable mattress! Also, once left for 24hrs as advised in the instructions, the mattress is now normal thickness. Overall this is excellent value for money.
